Page 38 - Behold the land of the Chaldeans; this people was not, till the Assyrian founded it for them that dwell in the wilderness: they set up the towers thereof, they raised up the palaces thereof; and he brought it to ruin.
Page 461 - The rose-coloured scentbottles, &c. , now commonly made, are composed of plain glass, flashed or coated with a very thin layer of the glass in question. I have myself made numerous experiments on this subject, and have been completely, and at last uniformly, successful, in producing glass of a fine crimson colour. One cause why so many persons have failed in the same attempt...
Page 61 - My strong impression is that the surface of the iron is oxidized, or that the superficial particles of the metal are in such relation to the oxygen of the electrolyte as to be equivalent to an oxidation ; and that having thus their affinity for oxygen satisfied, and not being dissolved by the acid under the circumstances, there is no renewal of the metallic surface no reiteration of the attraction of 'successive particles of the iron on the elements of successive portions of the electrolyte, and...
Page 145 - I followed them impatiently, and at 9 o'clock in the morning I had the happiness to find myself in possession of the giraffe. A premium was given to the hunter whose horse had first come up with the animal; and this reward is the more merited, as the laborious chase is pursued in the midst of brambles and thorny trees.
Page 177 - ... where he shows two scars at the distance of an inch and a half from each other, but without any appearance of inflammation or thickening of the integuments. The dog, after biting him, disappeared, and he does not know what became of him or of the fisherman. The wounds bled a good deal, but not being very deep, they soon healed, without any application. He took no remedy, except...
Page 146 - Arabs measured twenty-one French feet in height from the ears to the hoofs. Green herbs are also very agreeable to this animal ; but its structure does not admit of its feeding on them in the same manner as our domestic animals, such as the ox and the horse. It is obliged to straddle widely ; its two fore-feet are gradually stretched widely apart from each other, and its neck being then bent into a semicircular form, the animal is thus enabled to collect the grass. But on the instant that any noise...
Page 145 - ... and to secure pasturage for the camels of both sexes which we had brought with us in aid of the object of our chase. We deferred until the morrow the pursuit of the young Giraffe, which my companions assured me they would have no difficulty in again discovering. The Arabs are very fond of the flesh of this animal. I partook of their repast. The live embers were quickly covered with slices of the meat, which I found to be excellent eating. " On the following day, the 16th...
Page 460 - This change of colour is very remarkable, as it is obvious that no change of oxygenation can possibly take place during the recuisson. The art of tinging glass by protoxide of copper and flashing it on crown-glass, has of late years been revived by the Tyne Company in England, at Choisy in France*, and in Suabia in Germany, and in 1827 the Academy of Arts at Berlin gave a premium for an imperfect receipt. To what extent modern glass-painters make use of these new glasses I am ignorant ; the specimens...
Page 176 - These effects, not hitherto known or expected under this form, are only cases of the discharge which takes place through air between the charcoal terminations of the poles of a powerful battery, when they are gradually separated after contact. Then the passage is through heated air exactly as with common electricity, and Sir H.
